Quality of welds could be better. Fit is good. For replacing the stock cat on a Euro 5 spec R1 it is a good cheap alternative. Best feature is the ability to use stock can. Sounds good and throaty. If you don't want to spend alot on a slip on this is definitely the way to go. Probably sounds better anyway.

Thank you for the installation video. Really straightforward and easy to follow. I appreciate being able to order with confidence knowing what to expect when the parts come in.

Paired it with an Akra GP slip-on and servo buddy for my 2016 R1. Sounds utterly amazing.

It is an easy install, no modification is required for a 2015 YZF-R1(M), nice look especially when it burns blue, I got this for my Bike in Venezuela and all my fellow riders loved it, the product's quality is a 5/5. You will need to remove the servomotor and the engine trouble light eliminator device too

Awesome product, light weight looks awesome changing colors when heating up and sounds like a beast, it definitely is a head turner.

The how-to installation video on STG convinced me that this was the right exhaust mod for my R1. Simple to install, cost-effective way to add a bit of performance, and it uncorks the sound of the bike with the stock slip-on. Next step bodywork and 2018 track day season here I come.

P.S. Don't forget to pick up the servo buddy exhaust value eliminator.

The video installs on STG are game changers but the sound of the stock can and titanium M4 midpipe is something that must be heard in person. Wow! Very aftermarket sounding. Deep and throaty. Very easy to install and looks great on the bike. Highly recommended. I installed the block off plates the next day and they cleared up a lot of the coughing and backfire.
